The Hox gene family are examples of homeotic genes.
Homeotic genes are genes that when mutant cause a change in the spatial position of structures (change in address). wild-type fruit fly antennapedia mutant Box 4A
4
The Hox gene family are examples of homeotic genes.
The Hox gene products give the positional address along the Anterior-Posterior (A/P) axis in all animals. Box 4A
5
The Hox gene family are examples of homeotic genes.
The Hox genes encode a family of paralogous proteins that are sequence-specific DNA-binding transcription factors.
6
The Hox gene family are examples of homeotic genes.
The Hox proteins bind to response elements in the promoter DNA of target genes. The DNA-binding domain of the protein is called the homeodomain:

The Hox gene family are examples of homeotic genes.
Hox proteins work in a combinatorial manner to determine A/P axis address. Fig. 4.9
